Reports assignments that are used as a condition of an <code>if</code>, <code>while</code>, <code>for</code>, or
<code>do</code> statement, or a conditional expression.
<p>Although occasionally intended, this usage is confusing and may indicate a typo, for example, <code>=</code> instead of <code>==</code>.</p>
<p>The quick-fix replaces <code>=</code> with <code>==</code>.</p>
<p><b>Example:</b></p>
<pre><code>
  void update(String str, boolean empty) {
    // Warning: 'empty' is reassigned,
    // not compared to str.isEmpty()
    if (empty = str.isEmpty()) {
      ...
    }
  }
</code></pre>
<p>After the quick-fix is applied:</p>
<pre><code>
  void update(String str, boolean empty) {
    if (empty == str.isEmpty()) {
      ...
    }
  }
</code></pre>
